[Environment: Ubuntu 10.04]

I've just finished compiling Linux-2.6.20 and wanna make it work, so I think I should add something to my grub2, as I finished 

make modules_install
make install

in /boot/,I got 

vmlinuz-2.6.20
System.map-2.6.20
config-2.6.20

So I just tried

mkinitramfs -o initrd.img-2.6.20 2.6.20

Then the file initrd.img-2.6.20 was generated, but after I type 

update-grub2

That image file is not found! Does anyone know how to deal with this?

By the way,I really wonder from which files is initrd.img-2.6.20 generated? Because it seemed that I didn't even specify any source to generate this file.
